Rock testing

[René]

There is no difference Rene, I was just saying that the slight red color that is on the bottom of your clouds did not look realistic to me. But then I saw some real clouds with that same effect.

OK, haha. So i was right after all.

Im depressed now.

just impressing rock work!

Im depressed now. 

me too!

killer stuff René... great to see you sharing some insights!
cheers

Rene, fantastic work man.
Looking at your posts on the Mesa, I would like to know how you sharpened up the corners of the rock. Your original 2D height field has rounded sides yet the final has wonderfully crisp vertical corners and edges.

The heightfield was just used for the largest "base" shapes. All the detail comes from procedural displacements in Terragen, which is what allows for overhangs/non-planar features, and is responsible for the sharper features.

Try raising the basic shape and then add some huge fake stones (with or without an compute terrain in front); you get some sharp angled outcrops as well.

It's like Oshyan said; all of the displacements are procedural textures on top of the height field. I used vertically streched Voronoi for the main large displacements. I added a little warp too.
You could of course use (stretched)fake stones too.

Thank you.
Now please tell me everything else you know

Like some of the images in your portfolio very much too. Good work.

Thanks René,
I was playing with all sorts of noises and seeing your stretched voronoi makes a lot of sense. Can't wait to get home and try it out. (Travelling for work and not having TG4 to play with kills me)

Rene,
How do you put noise through a voronoi pattern like that? I have been trying for days.

Any clues would be appreciated.

A Voronoi 3D diff scaler(blue node) was used. I found a few clip files on this forum and combined them(without really understanding what i was doing.)
I hope this will put you in the right direction.

The scale input of noises can be a vector, so x,y and z can be different.

My recently posted file on columnar rocks uses the same technique. Though I've been struggling to get the same results as Rene   Might give an insight into how to do it though.

Thank you so much. VERY useful. I really appreciate the help.
